Hair Shedding vs Hair Loss: When Should You Be Concerned? - Medical Aesthetics & Skin Care Clinic in Singapore

Many patients use the terms “hair shedding” and “hair loss” interchangeably. Medically, they are not the same.

Understanding the difference is important in determining whether what you are experiencing is normal – or something that requires evaluation.

What is Hair Shedding?

Hair shedding refers to the normal daily falling of hair as part of the natural hair growth cycle.

On average, most individuals shed between 50 to 100 hairs per day. These hairs are usually in the telogen (resting) phase of the hair cycle and will fall regardless of whether you wash or comb your hair.

Shedding becomes pathological when it significantly exceeds normal amounts.

If hair fall increases to two to three times the usual amount, this condition is known as Telogen Effluvium.

If this increased shedding persists for longer than six months, it is classified as Chronic Telogen Effluvium.

Telogen effluvium is often triggered by stressors such as:

Illness
Surgery
Significant emotional stress
Hormonal shifts
Nutritional deficiencies

In many cases, the condition is reversible once the underlying trigger is addressed.

What Is Hair Loss?

Hair loss generally refers to a pathological process that affects hair density, hair structure, or follicle integrity.

Unlike temporary shedding, hair loss often involves progressive thinning or patterned hair reduction.

Hair loss can broadly be divided into two major categories.

Scarring Hair Loss

Scarring hair loss involves permanent destruction of hair follicles.

The follicle is replaced by fibrous tissue, meaning regrowth is no longer possible.

Diagnosis typically involves:

Trichoscopy
Scalp biopsy

Treatment depends on the specific condition and focuses on halting progression.

Non-Scarring Hair Loss (More Common)

Non-scarring forms are more common and often reversible, especially when detected early.

Telogen Effluvium

Characterised by excessive shedding, usually triggered by stress or systemic factors.

Androgenetic Alopecia

Also known as male or female pattern hair loss. This involves progressive follicle miniaturisation due to genetic and hormonal factors

Alopecia Areata

An autoimmune condition causing sudden, patchy hair loss.

Traction Alopecia

Caused by chronic tension from tight hairstyles. Early stages are reversible. Late stages may become scarring and permanent.

Trichotillomania

Hair loss caused by repetitive hair pulling.

Anagen Effluvium

Commonly associated with chemotherapy. This affects actively growing hairs.

Systemic Conditions

Hair loss may also be associated with:

Systemic lupus erythematosus (SLE)
Syphilis
Endocrine disorders such as thyroid disease

Identifying the underlying cause is critical to appropriate management.

When Should You Be Concerned?

You should seek evaluation if you notice:

A sudden increase in hair fall that is two to three times your usual amount
Persistent shedding lasting more than several months
Hair loss occurring in specific patterns
Hair loss occurring in specific patterns
Associated scalp symptoms such as redness, burning, or tenderness

Early assessment allows for earlier intervention – which improves outcomes significantly.

Final Thoughts

Some degree of hair shedding is completely normal. However, excessive or persistent shedding, or patterned hair thinning, may indicate an underlying condition that requires medical evaluation.

Distinguishing between normal shedding and pathological hair loss is the first step toward effective treatment.

If you are unsure whether your hair fall is within normal limits, a consultation with proper scalp assessment and trichoscopy can provide clarity.
